PRELIMINARY EXAMINATIONGENERAL DESCRIPTION AND INTENDED USE
GENERAL DESCRIPTION AND INTENDED USE
HI9814 is a durable, portable pH, conductivity, total
dissolved solids and temperature meter ideal for a wide
range of measurements encountered in hydroponics,
aquaponics or general agriculture applications. The HI9814
features a two button operation system and is simple to use.
The housing is waterproof and IP67 rated, ideal for harsh,
rugged conditions.
The supplied HI1285‑7 multiparameter probe measures
pH, EC/TDS, and temperature in one convenient, rugged
probe. A preamplifier is integrated into the probe to protect
the pH measurement from transient electrical noise.
Sources of electrical noise include ballasts used in lighting
and pumps to circulate water and nutrient solutions. Other
user‑selectable features include selectable TDS factors
of 0.5 and 0.7 as well as auto‑off to prolong battery life.

OPERATIONAL GUIDE
Each meter is supplied with batteries. Before using the
meter for the first time, open the battery compartment
and insert batteries, observing the polarity (see “Battery
Replacement“).
CONNECTING THE PROBE
Withthe meterturned off,connect theHI1285‑7 probetothe
DIN socket on the bottom of the meter by aligning the pins
and pushing in the plug firmly. Remove the protective cap
from the probe before taking any measurements.
TURNING THE METER ON
To turn the meter ON, press the button on
the front of the meter. If it does not turn on, make
sure that the batteries are properly installed in
their place.
OPERATIONAL GUIDE

The meter is provided with an active acoustic signal when
a key is pressed.
At start‑up the meter displays all LCD segments for a few
seconds, followed by the percentage indication of the remaining
battery life, displaying “WAIT“ until electrode check is in
process then the meter enters the normal measurement mode.
Note: The meter detects the presence and the type of the
probe at its input.
- If the probe is not connected the message “NO”
”PROBE“ appears alternatively on the tertiary LCD.
- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the third LCD line
with “---“ blinking on the first LCD line.
Note: A HI12943 pH probe may be used on this meter
but conductivity reading will not be displayed. “---“and
“NoEC“ message will be displayed.
- If the readings are out of range, the nearest range
limits are displayed blinking (e.g. -2.00 pH -5.0 °C).

ENTERING CALIBRATION MODE
Press and hold the button until ”POWER” and
tag is replaced by “QUICK“ tag if quick calibration
is selected from setup menu, or “PH STD“ tag or
“EC STD“ tag if standard calibration is selected from
setup menu. Release the button.
ENTERING SETUP MODE
From a measurement screen press and hold button until
“STD“ and tag is replaced by “SETUP“ and

OPERATIONAL GUIDE
METER SETUP
Setup mode allows configuration of parameters: Temperature unit,
Auto‑off, Calibration type, Beep confirmation tone, pH Resolution,
pH calibration information and TDS conversion factor.
• “TEMP“ is displayed on the tertiary LCD
line with the current temperature unit
(e.g. “TEMP °C“), for °C/°F selection,
use the SET button. After the temperature
unit has been selected, press to confirm and to enter the
“A-OFF“ selection.
• Use the SET button, to cycle through the
auto‑off choices: 8 minutes (“8”, default
value), 60 minutes (“60”) or disabled
(“---”). Press to confirm and to enter
the calibration type selection.
• tag is displayed. Use the SET
button to choose from “STD“ (standard
calibration) or “QUICK“ (one‑point
quick calibration). Press to confirm
and to enter the “BEEP“ selection.
• To switch the beep tone ON or OFF,
press the SET button; press
to confirm and to enter electrode
calibration information “INFO“
selection.
• To switch the electrode condition
indicator on the LCD ON or OFF, press
the SET button; press to exit setup
options; Change the set with the SET button, then press
to confirm and to enter TDS conversion factor “CONV“.
• “CONV“ is displayed on the tertiary
LCD line with the current TDS factor
(e.g. “0.50“), for selecting, “0.70“
TDS factor use the SET button. Press
to confirm and to return to normal mode.
pH MEASUREMENT
Make sure the meter has been calibrated before use.
If the probe is dry, soak it in HI70300 storage solution for
a minimum of 30 minutes to reactivate it.

10
If soiled, clean the electrode by soaking in cleaning solution
for 20 minutes, then rinse the tip and soak in storage solution
at least 30 minutes before use. Rinse the electrode off well
and shake off excess droplets. Recalibrate before using.
Submerge the probe in the sample to be tested while stirring
it gently. Wait until the tag on the LCD disappears.
The LCD displays the pH value (automatically compensated
for temperature) on the primary LCD, the EC, TDS or pH‑mV
value on the secondary LCD, while the third LCD line displays
the sample temperature.
If measurements are taken in
different samples successively rinse
the probe tip thoroughly in distilled
or deionized water to eliminate cross‑
contamination. For better accuracy, frequent calibration of
the pH sensor with the meter is recommended. In addition,
the meter must be recalibrated:
a) whenever the pH electrode is replaced.
b) after testing aggressive chemicals.
c) when high accuracy is required.
d) at least once a month.
e) after cleaning the probe.
SECOND LINE MEASUREMENT
While in measurement mode, press the SET button to
scroll between EC, TDS or mV of pH measurement on the
secondary LCD.
EC MEASUREMENT
Rinse the probe tip off with lots of clean water to remove
storage solution, buffers or samples. Shake off any droplets
that remained. Place the probe in the sample to be tested.
Use plastic beakers or containers to minimize any electro‑
magnetic interference. Tap the probe lightly on the bottom
of the container to remove air bubbles that may be trapped
inside the tip.
Wait for a few minutes for the temperature sensor to reach
thermal equilibrium, when the tag disappears.
